virtualbox.org

I am using VirtualBox version 6.1 with the official VirtualBox extension from the website.
Host OS is Windows 10 Pro 64 bit, guest OS is Windows 10 64 bit.
I deleted my old windows 10 VM and made a new one. Fresh ISO, fresh install of VirtualBox and the extension, etc.
Upon initial setup, the VM fails when the windows product key window opens. In the VirtualBox window, the VM says "Guru Meditation".
Logs are attached, help is greatly appreciated.

Fixed; I had too much memory dedicated to the guest.

Well, thanks for providing a zipped log on your first post. It's even complete, and zipped!

Yes, I would not give a VM more than 4096MB on that host. You should however increase graphics RAM to something reasonable (which 16MB is not). Max it out. And give the VM a second CPU core. Remember to install the Guest Additions.
